摘要

这项工作讨论了可能性,或者更确切地说,有效性,使用农业期货作为对冲手段,以尽量减少暴露于价格风险。该分析特别提到了“低发展国家”(LDCs),这些国家的农产品发挥着突出作用,在取消国家干预后进行的市场自由化进程决定了它们越来越容易受到价格波动的影响。据说,奈特的不确定性使生产商和投机者都更加厌恶风险,因此更加保守。特别是,当期货价格远高于预期现货价格(根据奈特不确定性进行调整)时,生产者的最佳头寸是对其生产进行完全对冲,而投机者的最佳头寸是完全不参与市场操作。我们只能观察到,如果一个生产者和一个投机者在市场上运作,那么可以达到的均衡有三种:完全交换、非交换和部分交换。获得三种均衡之一的可能性取决于两个不同主体各自的风险厌恶程度和奈特不确定性程度。进入资本市场是农业发展的一个关键因素,无论是在开办阶段还是在改良阶段。寻找新资本和新工具以便利进入市场需要金融市场运营者的高度信任,而这种信任往往因贷款的低盈利能力和与之相关的高风险而受到损害。事实上,农业活动的风险限制了传统金融的利益,减少了在转移到更有吸引力的替代用途后,该部门本身为数不多的剩余资源的资本可用性。因此,需要引进新的金融和保险技术和服务,例如保证农业部门获得增长所需的资本,同时为投资者提供有吸引力的回报机会。具体来说,报告指出,在这方面最有利的途径之一是在所有欧盟成员国实施特定的农业改革,将美国已经成功实施的风险管理技术引入农业

The agricultural futures market in low development countries: a policy to respond to the volatility of prices?
This work discusses the possibility, or rather the effectiveness, of the use of agricultural futures as a means of hedging to minimize exposure to price risk. In particular, the analysis refers to "low-development countries" (LDCs), countries in which agricultural products play a prominent role and in which the process of market liberalization, which took place following the removal of state intervention, is determining an increasing exposure to price volatility. Knight's uncertainty is said to make both producers and speculators more risk averse, hence more conservative. In particular, when the futures price is well above the expected spot price (adjusted for the Knightian uncertainty), the optimal position for the producer is a total hedge of his production, while the optimal position for the speculator consists in not operating at all in the market. We can limit ourselves to observing that if a single producer and a single speculator operate in the market, the equilibria that can be reached are three: of complete exchange, of non-exchange and of partial exchange. The possibility of obtaining one of the three equilibria depends on the degree of risk aversion and the degree of Knightian uncertainty possessed by each of the two different subjects. Access to the capital market is a crucial element for the development of agriculture, both in the start-up phase and in the improvement phase. The search for new capital and new tools to facilitate market access requires a high degree of trust on the part of financial market operators, a trust that is often compromised by the low profitability of loans and the high risk associated with them. The exposure to risk of agricultural activities limits, in fact, the interest of traditional finance, reducing the availability of capital to the few remaining resources within the sector itself after the flight to more attractive alternative uses. Hence the need to introduce new financial and insurance techniques and services, such as to guarantee the agricultural sector the capital necessary for growth and, at the same time, attractive return opportunities for investors. Specifically, it is stated that one of the most profitable paths to follow in this regard is implementation within all EU member states of particular agricultural reforms that introduce risk management techniques in agriculture already successfully implemented by the U.S.A.1
